Grandstream Networks GXW40XX user manual Important Settings, NAT Settings, Dtmf Methods

NOTE:

•WAN side HTTP access is disabled by default for security reasons. You can enable HTTP access on the configuration page by setting “WAN side HTTP access” to be YES.

•Initial access to the configuration pages is always from the LAN port. The instructions are listed above.

•The IVR announces 12 digits IP address, you need to strip out the leading “0” in the IP address. For ex. IP address: 192.168.001.014, you need to type in http://192.168.1.14 in the web browser.

Once the HTTP request is entered and sent from a web browser, the user will see a log-in screen. There are two default passwords for the login page:

User Level:	Password:	Web pages allowed:
End User Level	123	Only Status and Basic Settings
Administrator Level	Admin	Browse all pages

The password is case sensitive with maximum length of 25 characters. The factory default password for End User and administrator is “123” and “admin” respectively. Only an administrator can access the “ADVANCED SETTING”, “Profile 1”, “Profile 2” and “FXS PORTs” configuration pages. Please reference the GUI pages using the following link:

IMPORTANT SETTINGS

The end-user must configure the following settings according to the local environment. NOTE: Most settings on the web configuration pages are set to the default values.

NAT Settings

If you plan to keep the gateway within a private network behind a firewall, we recommend using STUN Server. The following three (3) settings are useful in the STUN Server scenario:

1.STUN Server (under Advanced Settings webpage)

Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the internet and enter it on this field. If using Public IP, keep this field blank.

2.Use Random Ports (under Advanced Settings webpage)

It really depends on your network settings, so set this parameter to Yes or No, whichever works. Generally if you have multiple IP devices under the same network, it should be set to Yes. If using a Public IP address, set this parameter to No.

3.NAT Traversal (under the Profile web pages)

Set this to Yes when gateway is behind firewall on a private network.

DTMF Methods

DTMF Settings are in Profile pages.

•DTMF in-audio

•DTMF via RTP (RFC2833)

•DTMF via SIP INFO

You can enable set priority of DTMF methods according to your preference, from Priority 1 to 3. This setting should be based on your server DTMF setting.
